Abstract
The utility model discloses a vertical single-stage single-suction submersible centrifugal pump body with symmetric dual-outlet volute chambers. Upper flanges are arranged at the upper part of the pump body and the two horizontal symmetric volute chambers are arranged in the pump body. The pump body has the characteristics as follows: the structure is simple and the radial force can keep balanced under any working condition; compared with a pump body with single volute chamber, the efficiency is basically the same as that of the pump body with single volute chamber, the high-efficiency range is wide, the vibration is small, the service life of a sliding bearing is long, the strength of the pump body is superior to that of the pump body with single volute chamber, and the thickness can be slightly smaller than the pump body with single volute chamber in the design process; and compared with a pump body with a spatial guide vane, the casting process is easy, and the pump body is more difficultly blocked due to the application of outlet diffusing pipes when the small pump body is cast.
Description
Technical field
The utility model belongs to the fluid conveying machine technical field, is specifically related to a kind of vertical single stage single suction submerged centrifugal pump symmetric double outlet volute chamber pump housing.
Background technique
The design of the traditional vertical one step single sucking submerged centrifugal pump pump housing mostly is the form of single outlet volute chamber form or spatial guide blade, single outlet volute chamber pump housing is under off-design behaviour, very large radial force is arranged, the efficient of the vertical submerged centrifugal pump of this pump housing and certain harmful effect is all arranged the working life of sliding bearing, and the pump body structure of spatial guide blade form is complicated, be not easy to cast and process, small dimension pump housing casting difficulty is large, and reject rate is high.
The model utility content
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of vertical single stage single suction submerged centrifugal pump symmetric double outlet volute chamber pump housing is provided.
The technological scheme that the utility model adopts for achieving the above object is: the vertical single stage single suction submerged centrifugal pump symmetric double outlet volute chamber pump housing, pump housing top are provided with upper flange, are provided with the volute chamber that two horizontal symmetrical are arranged in the described pump housing.
Also comprise in the described pump housing and two two import diffusing tubes that are arranged symmetrically with that volute chamber is corresponding.
Described exit cone is Way out spirality straight up, and the entrance location of described exit cone is positioned at the end of its corresponding volute chamber, and the outlet of described exit cone is connected with the upper flange of the pump housing.
Characteristics of the present utility model are: simple in structure, radial force can keep balance under any operating mode; It is compared with single volute chamber pump housing: efficient is basically identical, and higher efficiency range is wide, vibrates littlely, and sliding bearing long service life, pump housing intensity are better than single volute chamber pump housing, and during design, thickness can be slightly less than single volute chamber pump housing; Compare with the spatial guide blade form pump housing, casting easily, and during the casting small dimension pump housing, the more difficult obstruction of exit cone form.
Description of drawings
Fig. 1 is plan view of the present utility model;
Fig. 2 is plan view of the present utility model;
Fig. 3 is use schematic diagram of the present utility model.
Wherein: 1, upper flange 2, the pump housing 3, exit cone 4, volute chamber.
Embodiment
as Figure 1-3, the vertical single stage single suction submerged centrifugal pump symmetric double outlet volute chamber pump housing, the pump housing 2 tops are provided with upper flange 1, be provided with in the described pump housing 2 volute chamber 4 that two horizontal symmetrical arrange and with two two import diffusing tubes 3 that are arranged symmetrically with that volute chamber 4 is corresponding, described exit cone 3 is Way out spirality straight up, the entrance location of described exit cone 3 is positioned at the end of its corresponding volute chamber 4, the outlet of described exit cone 3 is connected with the upper flange 1 of the pump housing 2, the flow direction of the medium that impeller can be flowed out is changed into axial flow by radial flow, and the flow velocity of reduction liquid, increase the pressure energy of liquid, be arranged symmetrically with owing to being because of the volute chamber 4 of the pump housing 2 and exit cone 3, therefore its radial force can keep balance under any operating mode.
The above; it is only the better embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or changed according to the technical solution of the utility model and model utility design thereof, within all should being encompassed in protection domain of the present utility model.
